The universe’s most powerful cabal of villainy has formed right under the Earth’s Mightiest Heroes’ noses–and they never noticed! This group of fowl (get it!) villains, is the Pets of Evil Masters!

And they’re after world domination! Rocket must team-up with The Pet Avengers (much to his dismay) to face down the foes that no one else can (or will bother with) in this Earth-Shattering adventure that can only be told in the Mighty Marvel Manner!
